Abstract: The disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates beyond a 4G communication system, such as LTE. A method includes receiving, in a first search space and a second search space that are linked for PDCCH repetition, at least one PDCCH including DCI; and receiving a PDSCH scheduled by the DCI based on QCL information of a CORESET with a lower ID among a first CORESET associated with the first search space and a second CORESET associated with the second search space, in case that the DCI does not include a TCI field and a time offset between a reception of the DCI and the PDSCH is greater than or equal to a threshold.

Abstract: Accordingly, the embodiment herein is to provide a method for improving reliability of a PDCCH in a wireless network. The method includes receiving an enable PDCCH repetition signal from a UE, wherein the enable PDCCH repetition signal indicates a capability of the UE to support a PDCCH information transmission over a plurality of occasions. Further, the method includes configuring the UE using a RRC parameter by transmitting a PDCCH repetition scheme signal to the UE, where the PDCCH repetition scheme indicates the PDCCH information transmission over the plurality of occasions. Further, the method includes associating the plurality of TCI states to a the PDCCH information by configuring a MAC-CE.

Abstract: The disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates beyond a 4G communication system, such as LTE. A method includes receiving, by a UE, PDCCH information from a network entity, where the PDCCH information includes DCI and PDSCH information, and determining, by the UE, the default beam behavior based on a CORESET with a lowest ID among first and second CORESETs, in response to determining that a TCI state is not present in the DCI and the scheduling offset between reception of all transmission occasions of DL DCI and the corresponding PDSCH information of the serving cell is greater than or equal to the threshold.
